It's just another day as you are attending to the brothers as you always do when suddenly three of them propose to you.

Mammon: "Mc marry me and I'll make you the happiest demon alive!"

Leviathan: pushes mammon out of the way "No Mc pick me! I'm the better option!"

Beelzebub: gets in front of them "Mc I know I can provide you a happy life if you choose to marry me, but the choice is yours"
